# Finding the Volume of a Balloon

A helium balloon with a volume of 2.4 L contains 0.10 moles of gas at 25 degrees C and 1 atm of pressure. The balloon leaks 0.02 moles of gas until someone manages to seal the hole. What is the new volume of the balloon?

#### Solution Preview

The ideal gas law is PV=nRT.

We know:

P = 1 atm

V = 2.4 L

n = 0.10 mol

T = 25 C = 298 K

If you use the gas constant, R = 0.08208 ...

#### Solution Summary

This solution involves calculating the volume of a balloon.
